Test a Scala application

This example demonstrates the integration of Gitlab CI with Scala applications using SBT. Checkout the example project and build status.

Add .gitlab-ci.yml file to project

The following .gitlab-ci.yml should be added in the root of your repository to trigger CI:

image: java:8

before_script:
  - apt-get update -y
  - apt-get install apt-transport-https -y
  # Install SBT
  - echo "deb http://dl.bintray.com/sbt/debian /" | tee -a /etc/apt/sources.list.d/sbt.list
  - apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 642AC823
  - apt-get update -y
  - apt-get install sbt -y
  - sbt sbt-version

test:
  script:
    - sbt clean coverage test coverageReport

The before_script installs SBT and displays the version that is being used. The test stage executes SBT to compile and test the project. scoverage is used as an SBT plugin to measure test coverage.

You can use other versions of Scala and SBT by defining them in build.sbt.

Display test coverage in build

Add the Coverage was \[\d+.\d+\%\] regular expression in the Settings > Edit Project > Test coverage parsing project setting to retrieve the test coverage rate from the build trace and have it displayed with your builds.

Builds must be enabled for this option to appear.
